To who're may cease/cm:

Be known ii, A h? Emcee, a citizen 0 the Uh es, end e resident y of (herd and of lvlicscel-ero, in h Territory oillew J M o, heve invented a new improved vl ell-Pump of which the iiollowi'eg is is full, cleats exec-t dcsci'ipticn. a

4 The object of the invention is to provide e new awed improved well pump edepted to be lowered into the well to eny desired above ground so that the intersecting pistons cause the water to he lifted to any desired height, the water passing through the pump freely, and without spraying, whirling or ehrupt deflection, thereby reducing the friction of the weter to minimum.

A precticel embodiment of the invention is represented in the accompanying drewings forming d part of this specification, in which similar cherecters of reference indicate corresponding parts in. all the views.

Figure l is a plan View of the improved pump; Fig. 2 is a sectional pier; view of the some on the line 22 of Fig. i; Fig. 3 is s sectional side elevation of the same on the line 3'3 ofl ig. 1; Fig. Al is a cross section the top and bottom with outwardly-extending annular flanges B, B fitting the inside of the well C, the flange vB being tapered upward to hold sediment or other filling to seal the well around the ump. The said casing A is provided wit vertically disposed intcrsectm bores A, A open at'the top and bottom i'or-the entrance and exit of the water, as hereinafter more fully described. In the bores A, A ere mounted to turn the istons D, D, provided on their eri ohersl laces "with spirel piston heeds E, forming corresponding grooves E The spiral piston heed E of the piston D fits into the spiral groove oi? the piston D, and the spiral piston heed E fits into the spiral groove E of the istcn D, it being understood that the heads run or Specification of Letters Extent.

wind in opposite directions, as will be read ily understood by referenceto Fig. 3.

The pistons D and D are keyed or otherwise secured to the lower ends of the shafts h and F, provided with wheels G and G in mesh with each other and contained in a housing H having legs H. bolted to the top of the upper flange B of.thc pump casing A. The shaft F is the driving shaft and extends upward through a tube I screwed or otherwise secured to the top of the gear housing'lrl andextendin to the top 01 the well C,'t0 be conncctec with a suitable supporting means for suspending the pump the desired distance down in the well C.

The driving shaft- F is preferably made in sections and likewise the tube 1, that is, the sections 1 and l of the tube 1 are connected with each other by an interiorly threaded coupling 1 in which screw the ends of the sections 1, (see Fig. 5) and in which also his a guide bearing J through which extends the shoftF, terminating above the round top portion Jef the guide J in e polygonal terminal F 'engogmgg the correspondinglyshaped portion of a couphn F restlng on top of the guide J. The 0 ygonal end F of the next following shalt section F also engages the coupling F so that when the section F is rotated by suitable machinery located on the top of the well 0, then a 1'0- tary motion is transmitted to the sheft F to rotate the piston D. Now by having the shafts F and F connected with each other by the gear wheels G and G, it is evident that the piston 13" is rotated in unison with the piston D, to cause the water in which the pn-mp'is submerged to enter the lower end of the casing-[- and he forced upward in the grooves E, E. by the spiral piston heads E and E, so that the water finally passes out of the top of the casing A to accumulate in the well G on top of the flange B, so that the well is finally filled and the water overflows the well at the top thereof.

In order to protect the shafts F and F a minst grit, sediment end the like and provide ample journal beorings, use is made of bushings ll and l'ilfitting the shafts F and F between the ear wheels G and G and the pistons D5 the said bushings K and ii being provided at their upper ends with snnulsr flanges K, K seated in the ing H and forming step bearings the water to a minimum.

- also surrounds the shaft for the gear wheels G and G. A bushing L F in the top of the gearhousing H, and a bushing L in the form of a cap incloses the upper end of the shaft F in the top of the housing H, forming additional bearings for piston shafts as plainly indicated in, Fig. 3.

From the foregoing it will be seen that the wearing parts are completely protected against sediment, and consequently the pump is not liable to clog up, and by providing deep spiral grooves E IE it is evident that water bearing sediment can be readily elevated, as the sediment can freely pass through the spiral grooves with the water. i

1t will also be noticed that the water passes through the pump freely and at slow speed, without s raying, whirling or abrupt deflection, there y reducing the friction of As the pump is always submerged it prevents slip of water and avoids vacuum.

The pump shown ingly light in construction and combines great strength with durability, and the pump is very compact and can be readily installed or taken out in a few minutes. All

i the bearings and gear wheels are submerged in oil sup lied through the suspending tube 1 from t e top of the well. The driving shaft and bearings are protected against injury by the inclosing suspending tube 1, and hence the pump is not liable easily to get out of order.

As all the working parts, not submerged in oil, have a clearance, the wear and friction of the whole pump are reduced to a minimum, thereby increasing its durability and efficiency, and enabling the pump to be very cheaply manufactured and installed.

Having thus vdescribed my invention, 1 claim as new and desire to secure by Letters Patent:

In a pump, the combination witha casing having intersecting bores, each of which is freely open at both ends, of a support, a connection carrying said support from one end of the casing and constructed to permit passage of fluid freely through it, intermeshing spiral piston heads in said bores, shafts I for said piston heads having bearing in said sup ort, and intermeshing gears upon said sha ts held in said support.
